The entire disclosures of each of the above applications are fully incorporated herein by reference.

FIELD

The present disclosure relates to novel olefin polymerization catalyst compositions comprising olefin polymerization catalyst compound, optional activator, and organosilica material support, and uses thereof.

BACKGROUND

This section provides background information related to the present disclosure which is not necessarily prior art.

Supported olefin polymerization catalysts are of great use in industry. Hence, there is interest in finding new supported catalyst systems that increase the commercial usefulness of the catalyst and allow the production of polymers having improved properties.

Catalysts for olefin polymerization are often based on cyclopentadienyl based transition metal compounds as catalyst precursors, which are activated either with alumoxane or with an activator containing a non-coordinating anion.

Porous inorganic solids have found great utility as catalysts and separation media for industrial application. In particular, mesoporous materials, such as silicas and aluminas, having a periodic arrangement of mesopores are attractive materials for use in adsorption, separation and catalytic processes due to their uniform and tunable pores, high surface areas and large pore volumes. The pore structure of such mesoporous materials is large enough to adsorb large molecules and the pore wall structure can be as thin as about 1 nm. Further, such mesoporous materials are known to have large specific surface areas (e.g., 1000 m²/g) and large pore volumes (e.g., 1 cc/g). For these reasons, such mesoporous materials enable reactive catalysts, adsorbents composed of a functional organic compound, and other molecules to rapidly diffuse into the pores and therefore, can be advantageous over zeolites, which have smaller pore sizes.

Consequently, such mesoporous materials can be useful not only for catalysis of high-speed catalytic reactions, but also as large capacity adsorbents.

Mesoporous organosilica (MOS) supports are conventionally formed by the self-assembly of a silsequioxane precursor in the presence of a structure directing agent, porogen and/or framework element. The precursor is hydrolysable and condenses around the structure directing agent. For example, Landskron, K., et al. report the self-assembly of 1,3,5-tris[diethoxysila]cylcohexane [(EtO)₂SiCH₂]₃ in the presence of a base and the structure directing agent, cetyltrimethylammonium bromide. Landskron, K., et al., Science, 302:266-269 (2003). The citation of references herein does not constitute an admission that those references are prior art or have any relevance to the patentability of this description disclosed herein. All references cited in the Background and Description sections of this specification are hereby incorporated by reference in their entirety.

However, the use of a structure directing agent, such as a surfactant, in the preparation of an organosilica material, such as a MOS, requires a more complicated, energy intensive process that limits the ability to scale-up the process for industrial applications. Additionally, structure directing agents present during formation impact the morphology of the organosilica material product. Furthermore, introduction of additional agents or processing steps to remove structure directing agents from MOS can introduce additional reactive and undesirable compositions into the system, potentially leading to additional species that could cause catalyst poisoning.

There remains a need in the art for new and improved supported catalysts and catalyst systems for the polymerization of olefins to obtain new and improved polyolefins, polymerization processes, and the like. Such new and improved catalyst systems can desirably achieve specific polymer properties, such as high melting point, high molecular weights, increasing conversion or comonomer incorporation, or altering comonomer distribution without deteriorating the resulting polymer's properties. Thus, there is a need to provide organosilica materials having desirable pore size, pore volume and surface area, which can be prepared in the absence of a structure directing agent, a porogen and/or a framework element (aside from C, O, Si and hydrogen). Such materials will be described further herein. For more information, see also, U.S. Provisional Application No. 62/091,071 filed on Dec. 12, 2014 and U.S. Provisional Application No. 62/091,077 filed on Dec. 12, 2014, the disclosures of which were fully incorporated herein by reference above. Accordingly, new and improved supported catalyst systems for the polymerization of olefins are contemplated by the present disclosure, in order to achieve enhanced properties, such as molecular weight, and/or comonomer incorporation, typically along with improvements in catalyst function, such as activity, by way of non-limiting example.

Further, a “porogen” is understood to be a compound capable of forming voids or pores in the resultant organosilica material framework. As used herein, the term “structure directing agent” encompasses and is synonymous and interchangeable with the terms “templating agent” and “template.”

An “olefin,” alternatively referred to as “alkene,” is a linear, branched, or cyclic compound of carbon and hydrogen having at least one double bond. For purposes of this specification and the claims appended thereto, when a polymer or copolymer is referred to as comprising an olefin, the olefin present in such polymer or copolymer is the polymerized form of the olefin. For example, when a copolymer is said to have an “ethylene” content of 35 wt % to 55 wt %, it is understood that the mer unit in the copolymer is derived from ethylene in the polymerization reaction and said derived units are present at 35 wt % to 55 wt %, based upon the weight of the copolymer.

Molecular weight distribution (MWD), also referred to as polydispersity (PDI), is defined to be M_(w) divided by M_(n). Unless otherwise noted, all molecular weight units (e.g., M_(w), M_(n), M_(z)) are g/mol. The following abbreviations may be used herein: Me is methyl, Et is ethyl, Pr is propyl, cPr is cyclopropyl, nPr is n-propyl, iPr is isopropyl, Bu is butyl, nBu is normal butyl, iBu is isobutyl, sBu is sec-butyl, tBu is tert-butyl, Oct is octyl, Ph is phenyl, Bn is benzyl, MAO is methylalumoxane, dme is 1,2-dimethoxyethane, TMS is trimethylsilyl, TIBAL is triisobutylaluminum, TNOAL is tri(n-octyl)aluminum, THF (also referred to as thf) is tetrahydrofuran, RT is room temperature (and is 25° C. unless otherwise indicated), tol is toluene, EtOAc is ethyl acetate, Np is neopentyl, and Cy is cyclohexyl.

Ethylene is considered an α-olefin for purposes of certain aspects of the present disclosure. An oligomer is a polymer having a low molecular weight, such as M_(n) of less than 25,000 g/mol, or less than 2,500 g/mol, or a low number of mer units, such as 75 mer units or less or 50 mer units or less.

The term “continuous” means a system that operates without interruption or cessation. For example a continuous process to produce a polymer would be one where the reactants are continually introduced into one or more reactors and polymer product is continually withdrawn.

A “solution polymerization” means a polymerization process in which the polymer is dissolved in a liquid polymerization medium, such as an inert solvent or monomer(s) or their blends. A solution polymerization is typically homogeneous. A homogeneous polymerization is one where the polymer product is dissolved in the polymerization medium. Such systems are preferably not turbid as described in J. Vladimir Oliveira, C. Dariva and J. C. Pinto, Ind. Eng. Chem. Res. 29, 2000, 4627.

A “bulk polymerization” means a polymerization process in which the monomers and/or comonomers being polymerized are used as a solvent or diluent using little or no inert solvent as a solvent or diluent. A small fraction of inert solvent might be used as a carrier for catalyst and scavenger. A bulk polymerization system contains less than 25 wt % of inert solvent or diluent, preferably less than 10 wt %, preferably less than 1 wt %, preferably 0 wt %.

A “catalyst system” is the combination of at least one catalyst compound, an organosilica support material, an optional activator, and an optional co-activator. For the purposes of this invention and the claims thereto, when catalyst systems are described as comprising neutral stable forms of the components, it is well understood by one of ordinary skill in the art, that the ionic form of the component is the form that reacts with the monomers to produce polymers. For example, when “catalyst system” is used to describe a catalyst/activator/support combination before activation, it means the unactivated catalyst complex (precatalyst) together with an activator, support and, optionally, a co-activator. When it is used to describe such after activation, it means the support, the activated complex, and the activator or other charge-balancing moiety. The transition metal compound may be neutral as in a precatalyst, or a charged species with a counter ion as in an activated catalyst system.

Coordination polymerization is an addition polymerization in which successive monomers are added to the organometallic active center.

The terms “cocatalyst” and “activator” are used herein interchangeably and are defined to be any compound which can activate any one of the catalyst compounds herein by converting the neutral catalyst compound to a catalytically active catalyst compound cation.

Organosilica Materials

In certain aspects, the invention relates to organosilica materials used as catalyst support materials. The organosilica material supports may be a polymer formed of at least one monomer, as will be described further below. In certain variations, the organosilica material may be a polymer formed of multiple distinct monomers.

As used herein, and unless otherwise specified, “a bond to a silicon atom of another monomer” means the bond can advantageously displace a moiety (particularly an oxygen-containing moiety such as a hydroxyl, an alkoxy or the like), if present, on a silicon atom of another monomer so there may be a bond directly to the silicon atom of the another monomer thereby connecting the two monomers, e.g., via a Si—O—Si linkage. As used herein, and unless otherwise specified, “an oxygen atom bonded to a silicon atom of another monomer” means that the oxygen atom can advantageously displace a moiety (particularly an oxygen-containing moiety such as a hydroxyl), if present, on a silicon atom of the another monomer so the oxygen atom may be bonded directly to the silicon atom of the another monomer thereby connecting the two monomers, e.g., via a Si—O—Si linkage. For clarity, in the aforementioned bonding scenarios, the “another monomer” can be a monomer of the same type or a monomer of a different type.

Organosilica Material Characterization

In certain aspects, the invention relates to organosilica material supports that may be a polymer formed from a reaction of any of the monomers of Formulas (I)-(VI), although in certain alternative variations, the organosilica materials are not limited to only these monomers. Furthermore, in certain embodiments, the organosilica material support may be a polymer formed of multiple distinct monomers, including any combinations of monomers of Formula (I) with one or more monomers of Formulas (II)-(VI). As noted above, in certain alternative embodiments, the organosilica material support may be a polymer formed of one or more monomers of Formula (VI), with or without other monomers of Formulas (I)-(V).

The inventive technology thus uses the monomer building blocks described above to form an organosilane having a high surface area and high porosity without use of any structure directing agent (SDA), porogen. However, in certain aspects, the pores in the organosilane materials of the invention are not arranged in an ordered structure as they would be if formed with a structure directing agent (SDA). Conventional periodic mesoporous organosilicas (PMO) materials have highly ordered pore structures that occur by use of SDAs (typically surfactants) during reaction formations. In contrast, in certain aspects, the organosilica material support of the present disclosure may be formed without use of any SDAs or porogens as a template, while still exhibiting relatively ordered pore structures and desirably high surface area and porosity levels.

In various aspects, the organosilica materials described herein can be characterized as described in the following sections. Further description and characterization of suitable organosilica materials for use as catalyst supports can be found in “CO-FILED CASES” which are defined to be: 1) U.S. Ser. No. 14/966,001; filed Dec. 11, 2015; 2) U.S. Ser. No. 14/965,992; filed Dec. 11, 2015; 3) U.S. Ser. No. 14/965,984; filed Dec. 11, 2015; 4) U.S. Ser. No. 14/966,383; filed Dec. 11, 2015; 5) U.S. Ser. No. 14/966,015; filed Dec. 11, 2015; 6) U.S. Ser. No. 14/966,284; filed Dec. 11, 2015, which are incorporated herein by reference in their entireties.

X-Ray Diffraction Peaks

The organosilica material supports described herein can exhibit powder X-ray diffraction patterns with one broad peak between about 1 and about 4 degrees 2θ, particularly one peak between about 1 and about 3 degrees 2θ, or particularly one peak between about 1 and about 2 degrees 2θ. The organosilica materials can exhibit substantially no peaks in the range of about 0.5 to about 10 degrees 2θ, or about 0.5 to about 70 degrees 2θ, or about 2 to about 10 degrees 2θ, or about 2 to about 70 degrees 2θ, or about 3 to about 10 degrees 2θ, or about 3 to about 70 degrees 2θ.

Silanol Content

The organosilica material supports can have a silanol content that varies within wide limits, depending on the composition of the synthesis solution. The silanol content can conveniently be determined by solid state silicon NMR, more specifically by using solid state 29Si or ¹H NMR.

In various aspects, the organosilica material supports can have a silanol content of greater than about 5%. In certain embodiments, the silanol content can be greater than about 30% or greater than about 41%. The organosilica material supports may have a silanol content of about 5% to about 80%, or about 5% to about 50%, or about 5% to about 25%, or about 5% to about 10%, or about 10% to about 50%, or about 10% to about 20%, or about 20% to about 30%, or about 30% to about 50%.

Pore Size

The organosilica material supports described herein are advantageously in a mesoporous form. As indicated previously, the term mesoporous refers to solid materials having pores with a diameter within the range of from greater than or equal to about 2 nm to less than or equal to about 50 nm. The average pore diameter of the organosilica material can be determined, for example, using nitrogen adsorption-desorption isotherm techniques within the expertise of one of skill in the art, such as the BET (Brunauer Emmet Teller) method. Pore size can be measured by the Brunauer-Emmett-Teller (BET) method using adsorption-desorption of nitrogen (temperature of liquid nitrogen, 77 K) with a Micromeritics Tristar II 3020 instrument after degassing of the powders for 4 hrs. at 350° C. Typically, the samples are pre-treated with 120° C./vacuum/4 hours before the BET analysis is conducted. More information regarding the method can be found, for example, in S. Lowell et al., “Characterization of Porous Solids and Powders: Surface Area, Pore Size and Density,” Springer (2004).

The organosilica material supports can have an average pore diameter of about 0.2 nm to less than about 2.0 nm in certain variations. The organosilica material supports can advantageously have an average pore diameter within the mesopore range of about 2.0 nm to about 50 nm. The organosilica material supports can have an average pore diameter of 0.2 nm to about 50 nm, or about 1.0 nm to about 50 nm, or in the mesopore range of about 2.0 nm to about 50 nm, about 2.0 nm to about 40 nm, about 2.0 nm to about 30 nm, about 2.0 nm to about 20 nm, about 2.0 nm to about 10 nm, about 2.0 nm to about 5.0 nm, and about 2.0 nm to about 4.0 nm.

Using surfactant as a template to synthesize mesoporous materials can create highly ordered structure, e.g. well-defined cylindrical-like pore channels. In some circumstances, there may be no hysteresis loop observed from N₂ adsorption isotherm. In other circumstances, for instance where mesoporous materials can have less ordered pore structures, a hysteresis loop may be observed from N2 adsorption isotherm experiments. In such circumstances, without being bound by theory, the hysteresis can result from the lack of regularity in the pore shapes/sizes and/or from bottleneck constrictions in such irregular pores.

Surface Area

The surface area of the organosilica material supports can be determined, for example, using nitrogen adsorption-desorption isotherm techniques within the expertise of one of skill in the art, such as the BET (Brunauer Emmet Teller) method. This method may determine a total surface area, an external surface area, and a microporous surface area. As used herein, and unless otherwise specified, “total surface area” refers to the total surface area as determined by the BET method. As used herein, and unless otherwise specified, “microporous surface area” refers to microporous surface are as determined by the BET method. Surface area determined by the BET method uses adsorption-desorption of nitrogen (temperature of liquid nitrogen, 77 K) with a Micromeritics Tristar II 3020 instrument after degassing of the powders for 4 hrs. at 350° C. Typically, the samples are pre-treated with 120° C./vacuum/4 hours before the BET analysis is conducted. More information regarding the method can be found, for example, in S. Lowell et al., “Characterization of Porous Solids and Powders: Surface Area, Pore Size and Density,” Springer (2004).

In various embodiments, the organosilica material supports can have a total (e.g., BET) surface area greater than or equal to 2 m²/g to less than or equal to about 2,500 m²/g, about 50 m²/g to about 2,500 m²/g, about 100 m²/g to about 2,500 m²/g, about 200 m²/g to about 2,500 m²/g, about 300 m²/g to about 2,500 m²/g, or about 400 m²/g to about 2,500 m²g.

Pore Volume

The pore volume of the organosilica material supports described herein can be determined, for example, using nitrogen adsorption-desorption isotherm techniques within the expertise of one of skill in the art, such as the total (Brunauer Emmet Teller) method described above. The organosilica material supports can have a pore volume of about 0.1 cm³/g to about 10.0 cm³/g, about 0.1 cm³/g to about 5.0 cm³/g, about 0.1 cm³/g to about 2.0 cm³/g, about 0.1 cm³/g to about 1.0 cm³/g, or about 0.1 cm³/g to about 0.5 cm³/g.

In a particular embodiment, the organosilica material supports can have a pore volume of about 0.1 cm³/g to about 5.0 cm³/g, particularly about 0.1 cm³/g to about 3.0 cm³/g, particularly about 0.2 cm³/g to about 2.5 cm³/g, or particularly about 0.2 cm³/g to about 1.5 cm³/g.

Particle Size

The organosilica material supports can have an average particle size in the range of from greater than or equal to about 5 m to about 500 m. Average particle size, also referred to as “particle size,” or “particle diameter” is determined using a Mastersizer™ 3000 (range of 1 to 3500 m) available from Malvern Instruments, Ltd. Worcestershire, England. Particle size distribution via laser sizing can also be a method of measuring ranges of average particles sizes and particle dispersion.

Dried Particles

The organosilica material support material may be dry, that is, free of absorbed water. Drying of the organosilica material can be effected by heating or calcining at a range of greater than or equal to about 100° C. to less than or equal to about 1000° C. for a time of about 1 minute to about 100 hours. The calcined material preferably has at least some reactive oxygen containing groups, such as hydroxyl (OH) groups.

Aqueous Mixture

The organosilica material supports described herein may be made using essentially no structure directing agent or porogen. Thus, the aqueous mixture contains essentially no added structure directing agent and/or no added porogen.

As used herein, “no added structure directing agent,” and “no added porogen” means either (i) there is no component present in the synthesis of the organosilica material that aids in and/or guides the polymerization and/or polycondensing and/or organization of the building blocks that form the framework of the organosilica material; or (ii) such component is present in the synthesis of the organosilica material in a minor, or a non-substantial, or a negligible amount such that the component cannot be said to aid in and/or guide the polymerization and/or polycondensing and/or organization of the building blocks that form the framework of the organosilica material. Further, “no added structure directing agent” is synonymous with “no added template” and “no added templating agent.”

Exemplary bases can include, but are not limited to, sodium hydroxide, potassium hydroxide, lithium hydroxide, pyridine, pyrrole, piperazine, pyrrolidine, piperidine, picoline, monoethanolamine, diethanolamine, dimethylmonoethanolamine, monomethyldiethanolamine, triethanolamine, diazabicyclooctane, diazabicyclononane, diazabicycloundecene, tetramethylammonium hydroxide, tetraethylammonium hydroxide, tetrapropylammonium hydroxide, tetrabutylammonium hydroxide, ammonia, ammonium hydroxide, methylamine, ethylamine, propylamine, butylamine, pentylamine, hexylamine, octylamine, nonylamine, decylamine, N,N-dimethylamine, N,N-diethylamine, N,N-dipropylamine, N,N-dibutylamine, trimethylamine, triethylamine, tripropylamine, tributylamine, cyclohexylamine, trimethylimidine, 1-amino-3-methylbutane, dimethylglycine, 3-amino-3-methylamine, and the like. These bases may be used either singly or in combination. In a particular embodiment, the base can comprise or be sodium hydroxide and/or ammonium hydroxide.

In a particular embodiment comprising an acid, the pH can be from about 0.01 to about 6.0, about 0.2 to about 6.0, about 0.2 to about 5.0 or about 0.2 to about 4.5.

Exemplary acids can include, but are not limited to, inorganic acids such as hydrochloric acid, nitric acid, sulfuric acid, hydrofluoric acid, phosphoric acid, boric acid and oxalic acid; and organic acids such as acetic acid, propionic acid, butanoic acid, pentanoic acid, hexanoic acid, heptanoic acid, octanoic acid, nonanoic acid, decanoic acid, oxalic acid, maleic acid, methylmalonic acid, adipic acid, sebacic acid, gallic acid, butyric acid, mellitic acid, arachidonic acid, shikimic acid, 2-ethylhexanoic acid, oleic acid, stearic acid, linoleic acid, linolenic acid, salicylic acid, benzoic acid, p-amino-benzoic acid, p-toluenesulfonic acid, benzenesulfonic acid, monochloroacetic acid, dichloroacetic acid, trichloroacetic acid, trifluoroacetic acid, formic acid, malonic acid, sulfonic acid, phthalic acid, fumaric acid, citric acid, tartaric acid, succinic acid, itaconic acid, mesaconic acid, citraconic acid, malic acid, a hydrolysate of glutaric acid, a hydrolysate of maleic anhydride, a hydrolysate of phthalic anhydride, and the like. These acids may be used either singly or in combination. In a particular embodiment, the acid can comprise or be hydrochloric acid.

In various aspects, adjusting the pH of the aqueous mixture can affect the total surface area, microporous surface area and pore volume of the organosilica material support made. Thus, the porosity of the organosilica material may be adjusted by adjusting the pH of the aqueous mixture.

For example, when the aqueous mixture is basic and has a pH between about 8 to about 14, in particular about 9 to about 14, the organosilica material support made may have one or more of the following characteristics: a) a total surface area of about 200 m²/g to about 1800 m²/g, particularly about 300 m²/g to about 1700 m²/g, and particularly about 400 m²/g to about 1700 m²/g; b) a microporous surface area of about 0 m²/g to about 700 m²/g, and particularly about 0 m²/g to about 700 m²/g; and c) a pore volume of about 0.2 cm³/g to about 3 cm³/g, and particularly of about 0.8 cm³/g to about 1.4 cm³/g.

When the aqueous mixture is acidic and has a pH between about 0.1 to about 7, particularly about 0.1 to about 5, particularly about 0.1 to about 4.5, the organosilica material made may have one or more of the following characteristics: a) a total surface area of about 100 m²/g to about 1500 m²/g, particularly about 100 m²/g to about 900 m²/g, and particularly about 200 m²/g to about 900 m²/g; b) a microporous surface area of about 100 m²/g to about 600 m²/g, and particularly about 0 m²/g to about 500 m²/g; and c) a pore volume of about 0.1 cm³/g to about 1.2 cm³/g, and particularly of about 0.1 cm³/g to about 0.6 cm³/g.

Thus, the total surface area of an organosilica material support made with a basic aqueous mixture may increase when compared to an organosilica material made with an acidic aqueous mixture. Further, the pore volume of an organosilica material support made with a basic aqueous mixture may increase when compared to an organosilica material made with an acidic aqueous mixture. However, the microporous surface area of an organosilica material support made with a basic aqueous mixture may decrease when compared to an organosilica material made with an acidic aqueous mixture.

Aging the Solution

The solution formed in the methods described herein can be aged for at least about 4 hours. The solution formed in the methods described herein can be aged for about 4 hours to about 144 hours (6 days), or about 96 hours (4 days) to about 120 hours (5 days), or about 120 hours (5 days) to about 144 hours (6 days). The solution formed in the method can be aged at temperature of about 10° C. to about 300° C., about 50° C. to about 300° C., about 100° C. to about 300° C., 130° C. to about 250° C., about 130° C. to about 200° C., about 130° C. to about 150° C., or about 130° C. to about 140° C. In various aspects, adjusting the aging time and/or aging temperature of the solution formed in the methods described herein can affect the total surface area, microporous surface area, pore volume, pore radius and pore diameter of the organosilica material made. Thus, the porosity of the organosilica material may be adjusted by adjusting aging time and/or temperature.

For example, when the solution is aged for about 1 hour to about 7 hours (e.g., 1, 2, 3, 4, 5, 6 hours) at a temperature of about 80° C. to about 100° C. (e.g., 80° C., 85° C., 90° C., 95° C., etc.), the organosilica material support may have one or more of the following: a) a total surface area of about 200 m²/g to about 1400 m²/g, particularly about 400 m2/g to about 1300 m²/g, and particularly about 400 m²/g to about 1200 m²/g; b) a microporous surface area of about 200 m²/g to about 600 m²/g, particularly about 200 m²/g to about 500 m²/g; c) a pore volume of about 0.2 cm³/g to about 1.0 cm³/g, particularly about 0.2 cm³/g to about 0.8 cm³/g; and d) an average pore radius of about 0.5 nm to about 2.0 nm, particularly about 0.5 nm to about 2.0 nm, and particularly about 1.0 nm to about 1.5 nm.

When the solution is aged for greater than about 7 hours to about 150 hours (e.g., 23, 48, 72, 144 hours) at a temperature of about 80° C. to about 100° C. (e.g., 80° C., 85° C., 90° C., 95° C., etc.), the organosilica material support may have one or more of the following: a) a total surface area of about 600 m²/g to about 1400 m²/g, particularly about 800 m²/g to about 1400 m²/g, and particularly about 800 m²/g to about 1200 m²/g; b) substantially no microporous surface area; c) a pore volume of about 0.8 cm³/g to about 1.4 cm³/g, particularly about 0.9 cm³/g to about 1.4 cm³/g; and d) an average pore radius of about 1.0 nm to about 4.0 nm, particularly about 1.0 nm to about 4.0 nm.

When the solution is aged for about 1 hour to about 7 hours (e.g., 1, 2, 3, 4, 5, 6 hours) at a temperature of about 110° C. to about 130° C. (e.g., 110° C., 115° C., 120° C., 125° C., etc.), the organosilica material support may have one or more of the following: a) a pore volume of about 1.0 cm³/g to about 1.8 cm³/g, particularly about 1.2 cm³/g to about 1.8 cm³/g, particularly about 1.4 cm³/g to about 1.7 cm³/g; and b) an average pore diameter of about 2.0 nm to about 8.0 nm, particularly 4.0 nm to about 6.0 nm.

When the solution is aged for greater than about 7 hours to about 150 hours (e.g., 23, 48, 72, 144 hours) at a temperature of about 110° C. to about 130° C. (e.g., 110° C., 115° C., 120° C., 125° C., etc.), the organosilica material support may have one or more of the following: a) a pore volume of about 1.0 cm³/g to about 1.8 cm³/g, particularly about 1.2 cm³/g to about 1.8 cm³/g; and b) an average pore diameter of about 8.0 nm to about 16.0 nm, particularly about 10.0 nm to about 16.0 nm, particularly about 10.0 nm to about 14.0 nm.

Thus, at shorter aging times (e.g., 7, 6, 5, 4 hours, etc.) the surface area of an organosilica material made is microporous and mesoporous, but as aging time increase, the surface area transitions to primarily mesoporous. Further, as aging time increases, pore volume, average pore radius and average pore diameter increases. Increasing aging temperature along with aging time, accelerates the above-described surface area transition and increase in pore volume, average pore radius and average pore diameter.

The methods described herein comprise drying the pre-product to produce an organosilica material support. In certain variations, the pre-product may be a gel.

In some embodiments, the pre-product (e.g., gel) formed in the method can be dried at a temperature of about 50° C. to about 600° C. In a particular embodiment, the pre-product (e.g., gel) formed in the method can be dried at temperature from about 70° C. to about 200° C.

The pre-product (e.g., gel) formed in the method can be dried in a N₂ and/or air atmosphere.

Additional Organosilica Support Processing Steps

The organosilica material support material is dry, that is, free of absorbed water. Drying of the support material can be effected by heating or calcining at about 100° C. to about 1000° C., preferably at least about 600° C. When the support material is an organosilica, it is typically heated to about 200° C. to about 850° C.; and for a time of about 1 minute to about 100 hours, from about 12 hours to about 72 hours, or from about 24 hours to about 60 hours.

In some embodiments, as noted above, the method can further comprise calcining the organosilica material to obtain a silica material. The calcining can be performed in air or an inert gas, such as nitrogen or air enriched in nitrogen. Calcining can take place at a temperature of at least about 175° C., for example, calcining can be performed at a temperature of about 175° C. to about 650° C.

The calcined support material comprising the organosilica material support may then be contacted with at least one polymerization catalyst comprising at least one metallocene compound and an activator.

Introducing Additional Catalyst Metals and Activators

In various embodiments, the organosilica material support can further comprise at least one catalyst metal incorporated within the pores of the organosilica material support, as will be described below. Exemplary catalyst metals can include, but are not limited to, a Group 6 element, a Group 8 element, a Group 9 element, a Group 10 element or a combination thereof. Exemplary Group 6 elements can include, but are not limited to, chromium, molybdenum, and/or tungsten, particularly including molybdenum and/or tungsten. Exemplary Group 8 elements can include, but are not limited to, iron, ruthenium, and/or osmium. Exemplary Group 9 elements can include, but are not limited to, cobalt, rhodium, and/or iridium, particularly including cobalt. Exemplary Group 10 elements can include, but are not limited to, nickel, palladium and/or platinum.

The catalyst metal can be incorporated into the organosilica material by any convenient method, such as by impregnation, by ion exchange, or by complexation to surface sites. The catalyst metal so incorporated may be employed to promote any one of a number of catalytic transformations commonly conducted in petroleum refining or petrochemicals production.

Examples of such catalytic processes can include, but are not limited to, hydrogenation, dehydrogenation, aromatization, aromatic saturation, hydrodesulfurization, olefin oligomerization, polymerization, hydrodenitrogenation, hydrocracking, naphtha reforming, paraffin isomerization, aromatic transalkylation, saturation of double/triple bonds, and the like, as well as combinations thereof.

Thus, in another embodiment, a catalyst material comprising the organosilica material described herein is provided. The catalyst material may optionally comprise a binder. Suitable binders, include but are not limited to silica, alumina, zirconia, titania, silica-alumina, cerium oxide, magnesium oxide, or combinations thereof. Thus, in another embodiment, a catalyst material comprising the organosilica material described herein is provided.

In some embodiments, the organosilica material can further comprise cationic metal sites incorporated into the network structure. Such cationic metal sites may be incorporated by any convenient method, such as impregnation or complexation to the surface, through an organic precursor, or by some other method. This organometallic material may be employed in a number of hydrocarbon separations conducted in petroleum refining or petrochemicals production. Examples of such compounds to be desirably separated from petrochemicals/fuels can include olefins, paraffins, aromatics, and the like.

The organosilica material can further comprise a surface metal incorporated within the pores of the organosilica material. The surface metal can be selected from a Group 1 element, a Group 2 element, a Group 13 element, and a combination thereof. When a Group 1 element is present, it can preferably comprise or be sodium and/or potassium. When a Group 2 element is present, it can include, but may not be limited to, magnesium and/or calcium. When a Group 13 element is present, it can include, but may not be limited to, boron and/or aluminum.

One or more of the Groups 1, 2, 6, 8-10 and/or 13 elements may be present on an exterior and/or interior surface of the organosilica material. For example, one or more of the Groups 1, 2 and/or 13 elements may be present in a first layer on the organosilica material and one or more of the Groups 6, 8, 9 and/or 10 elements may be present in a second layer, e.g., at least partially atop the Group 1, 2 and/or 13 elements. Each only one or more Groups 6, 8, 9 and/or 10 elements may present on an exterior and/or interior surface of the organosilica material. The surface metal(s) can be incorporated into/onto the organosilica material by any convenient method, such as by impregnation, deposition, grafting, co-condensation, by ion exchange, and/or the like.

In certain embodiments, the support material, having reactive surface groups, typically hydroxyl groups, may be slurried in a non-polar solvent and the resulting slurry is contacted with a solution of a catalyst compound and optionally an activator. In certain variations, the catalyst compound comprises a metallocene compound, so that the solution comprises a metallocene compound. In some embodiments, the slurry of the support material is first contacted with the activator for a period of time in the range of from about 0.5 hours to about 24 hours, from about 2 hours to about 16 hours, or from about 4 hours to about 8 hours. The solution of the catalyst compound, e.g., metallocene compound, is then contacted with the isolated support/activator. In some embodiments, the supported catalyst system is generated in situ. In alternate embodiments, the slurry of the support material is first contacted with the catalyst compound for a period of time in the range of from about 0.5 hours to about 24 hours, from about 2 hours to about 16 hours, or from about 4 hours to about 8 hours. The slurry of the supported metallocene compound is then contacted with the activator solution.

The mixture of the metallocene, activator and support is heated from greater than or equal to about 0° C. to less than or equal to about 70° C., preferably to about 23° C. to about 60° C., preferably at room temperature. Contact times typically range from about 0.5 hours to about 24 hours, from about 2 hours to about 16 hours, or from about 4 hours to about 8 hours.

Suitable non-polar solvents are materials in which the activator and the catalyst compound, e.g., metallocene compound, are at least partially soluble and which are liquid at reaction temperatures. Useful non-polar solvents are alkanes, such as isopentane, hexane, n-heptane, octane, nonane, and decane, although a variety of other materials including cycloalkanes, such as cyclohexane, aromatics, such as benzene, toluene, and ethylbenzene, may also be employed.

A simple screening method such as by ¹H or ¹³C NMR, known to those of ordinary skill in the art, can be used to determine which transition metal compounds are compatible. It is preferable to use the same activator for the transition metal compounds, however, two different activators, such as a non-coordinating anion activator and an alumoxane, can be used in combination, as described further below. If one or more transition metal compounds contain an X⁶ ligand which is not a hydride, hydrocarbyl, or substituted hydrocarbyl, then the alumoxane should be contacted with the transition metal compounds prior to addition of the non-coordinating anion activator.

Such oxadiazole catalyst compounds as described above are known in the art and any are suitable for use herein. Such catalysts are described in, but not limited to, PCT Publication WO 2010/132811, incorporated herein by reference.

Where two catalyst compounds are used, the two metal compounds (pre-catalysts) may be used in any ratio. Preferred molar ratios of (A) metal compound to (B) metal compound fall within the range of (A:B) 1:1000 to 1000:1, alternatively 1:100 to 500:1, alternatively 1:10 to 200:1, alternatively 1:1 to 100:1, and alternatively 1:1 to 75:1, and alternatively 5:1 to 50:1. The particular ratio chosen will depend on the exact pre-catalysts chosen, the method of activation, and the end product desired. In a particular embodiment, when using the two pre-catalysts, where both are activated with the same activator, useful mole percentages, based upon the molecular weight of the pre-catalysts, are about 10 to about 99.9% A to about 0.1 to about 90% B, alternatively about 25 to about 99% A to about 0.5 to about 50% B, alternatively about 50 to about 99% A to about 1 to about 25% B, and alternatively about 75 to about 99% A to about 1 to about 10% B.

Typically, the catalyst compound is present on the catalyst support at from 0.01 micromols of catalyst per gram of support to 100 micromols of catalyst per gram of support (preferably from 0.1 micromols of catalyst per gram of support to 10 micromols of catalyst per gram of support, preferably from 1 micromols of catalyst per gram of support to 5 micromols of catalyst per gram of support, preferably from 3 micromols of catalyst per gram of support to 5 micromols of catalyst per gram of support.

B. Catalyst Binder

The catalyst material may optionally comprise a binder. Suitable binders, include but are not limited to silica, alumina, zirconia, titania, silica-alumina, cerium oxide, magnesium oxide, or combinations thereof. Thus, in another embodiment, an organosilica material comprising a catalyst material described herein is provided.

VI. ACTIVATORS

In addition to the organosilica support and catalyst(s) described above, the catalyst system according to the present disclosure includes one or more activator compounds.

After the catalyst complexes described above are synthesized, catalyst compounds may be activated by combining them with activators in any manner known in the art by supporting them for use in slurry or gas phase polymerization. Non-limiting activators, for example, include alumoxanes, aluminum alkyls, ionizing activators, which may be neutral or ionic, and conventional-type cocatalysts. Preferred activators typically include alumoxane compounds, modified alumoxane compounds, and ionizing anion precursor compounds that abstract a reactive, σ-bound, metal ligand making the metal complex cationic and providing a charge-balancing noncoordinating or weakly coordinating anion.

After the catalyst complexes described above are synthesized, catalyst compounds may be activated by combining them with activators in any manner known in the art by supporting them for use in slurry or gas phase polymerization. Non-limiting activators, for example, include alumoxanes, aluminum alkyls, ionizing activators, which may be neutral or ionic, and conventional-type cocatalysts. Preferred activators typically include alumoxane compounds, modified alumoxane compounds, and ionizing anion precursor compounds that abstract a reactive, σ-bound, metal ligand making the metal complex cationic and providing a charge-balancing noncoordinating or weakly coordinating anion.

A. Alumoxane Activators

In one embodiment, alumoxane activators are utilized as an activator in the catalyst system. Alumoxanes are generally oligomeric compounds containing —Al(R¹)—O— sub-units, where R¹ is an alkyl group. Examples of alumoxanes include methylalumoxane (MAO), modified methylalumoxane (MMAO), ethylalumoxane and isobutylalumoxane. Alkylalumoxanes and modified alkylalumoxanes are suitable as catalyst activators, particularly when the abstractable ligand is an alkyl, halide, alkoxide or amide. Mixtures of different alumoxanes and modified alumoxanes may also be used. It may be preferable to use a visually clear methylalumoxane. A cloudy or gelled alumoxane can be filtered to produce a clear solution or clear alumoxane can be decanted from the cloudy solution. A useful alumoxane is a modified methyl alumoxane (MMAO) cocatalyst type 3A (commercially available from Akzo Chemicals, Inc. under the trade name Modified Methylalumoxane type 3A and described in U.S. Pat. No. 5,041,584).

When the activator is an alumoxane (modified or unmodified), some embodiments select the maximum amount of activator typically at up to a 5000-fold molar excess Al/M over the catalyst compound (per metal catalytic site). The minimum activator-to-catalyst-compound is a 1:1 molar ratio. Alternate preferred ranges include from 1:1 to 500:1, alternately from 1:1 to 200:1, alternately from 1:1 to 100:1, or alternately from 1:1 to 50:1.

In an alternate embodiment, little or no alumoxane is used in the polymerization processes described herein. Preferably, alumoxane is present at zero mole %, alternately the alumoxane is present at a molar ratio of aluminum to catalyst compound transition metal less than 500:1, preferably less than 300:1, preferably less than 100:1, preferably less than 1:1.

B. Non-Coordinating Anion Activators

A non-coordinating anion (NCA) is defined to mean an anion either that does not coordinate to the catalyst metal cation or that does coordinate to the metal cation, but only weakly. The term NCA is also defined to include multicomponent NCA-containing activators, such as N,N-dimethylanilinium tetrakis(pentafluorophenyl)borate, that contain an acidic cationic group and the non-coordinating anion. The term NCA is also defined to include neutral Lewis acids, such as tris(pentafluorophenyl)boron, that can react with a catalyst to form an activated species by abstraction of an anionic group. An NCA coordinates weakly enough that a neutral Lewis base, such as an olefinically or acetylenically unsaturated monomer can displace it from the catalyst center. Any metal or metalloid that can form a compatible, weakly coordinating complex may be used or contained in the noncoordinating anion. Suitable metals include, but are not limited to, aluminum, gold, and platinum. Suitable metalloids include, but are not limited to, boron, aluminum, phosphorus, and silicon. A stoichiometric activator can be either neutral or ionic. The terms ionic activator, and stoichiometric ionic activator can be used interchangeably. Likewise, the terms neutral stoichiometric activator, and Lewis acid activator can be used interchangeably. The term non-coordinating anion includes neutral stoichiometric activators, ionic stoichiometric activators, ionic activators, and Lewis acid activators.

“Compatible” non-coordinating anions are those which are not degraded to neutrality when the initially formed complex decomposes. Further, the anion will not transfer an anionic substituent or fragment to the cation so as to cause it to form a neutral transition metal compound and a neutral by-product from the anion. Non-coordinating anions useful in accordance with this invention are those that are compatible, stabilize the transition metal cation in the sense of balancing its ionic charge at +1, and yet retain sufficient ability to permit displacement during polymerization.

In certain aspects, an ionizing or stoichiometric activator, neutral or ionic, such as tri (n-butyl) ammonium tetrakis (pentafluorophenyl) borate, a tris perfluorophenyl boron metalloid precursor or a tris perfluoronaphthyl boron metalloid precursor, polyhalogenated heteroborane anions (PCT International Publication No. WO 98/43983), boric acid (U.S. Pat. No. 5,942,459), or combination thereof can be used. Neutral or ionic activators alone or in combination with alumoxane or modified alumoxane activators can also be used.

The catalyst systems of this invention can include at least one non-coordinating anion (NCA) activator.

The cation component, Z²⁴ _(d) ⁺ may include Bronsted acids such as protons or protonated Lewis bases or reducible Lewis acids capable of protonating or abstracting a moiety, such as an alkyl or aryl, from portions of the catalyst precursor, resulting in a cationic transition metal species.

The activating cation Z²⁴ _(d) ⁺ may also be a moiety such as silver, tropylium, carboniums, ferroceniums and mixtures, preferably carboniums and ferroceniums. Most preferably Z²⁴ _(d) ⁺ is triphenyl carbonium. Preferred reducible Lewis acids can be any triaryl carbonium (where the aryl can be substituted or unsubstituted, such as those represented by the formula: (Ar₃C⁺), where Ar is aryl or aryl substituted with a heteroatom, a C₁ to C₄₀ hydrocarbyl, or a substituted C₁ to C₄₀ hydrocarbyl), preferably the reducible Lewis acids in formula above as “Z²⁴” include those represented by the formula: (Ph₃C), where Ph is a substituted or unsubstituted phenyl, preferably substituted with C₁ to C₄₀ hydrocarbyls or substituted a C₁ to C₄₀ hydrocarbyls, preferably C₁ to C₂₀ alkyls or aromatics or substituted C₁ to C₂₀ alkyls or aromatics, preferably V is a triphenylcarbonium.

The anion component A_(d) ⁻ includes those having the formula [M^(8k+)Q_(n)]_(d) ⁻ wherein k is 1, 2, or 3; n is 1, 2, 3, 4, 5, or 6 (preferably 1, 2, 3, or 4); n−k=d; M⁸ is an element selected from Group 13 elements, preferably boron or aluminum, and Q is independently a hydride, bridged or unbridged dialkylamido, halide, alkoxide, aryloxide, hydrocarbyl, substituted hydrocarbyl, halocarbyl, substituted halocarbyl, and halosubstituted-hydrocarbyl radicals, said Q having up to 20 carbon atoms with the proviso that in not more than 1 occurrence is Q a halide.

Illustrative, but not limiting examples of boron compounds which may be used as an activating cocatalyst are the compounds described as (and particularly those specifically listed as) activators in U.S. Pat. No. 8,658,556, which is incorporated by reference herein.

Most preferably, the ionic stoichiometric activator Z²⁴ _(d) ⁺(A^(d−)) is one or more of N,N-dimethylanilinium tetra(perfluorophenyl)borate, N,N-dimethylanilinium tetrakis(perfluoronaphthyl)borate, N,N-dimethylanilinium tetrakis(perfluorobiphenyl)borate, N,N-dimethylanilinium tetrakis(3,5-bis(trifluoromethyl)phenyl)borate, triphenylcarbenium tetrakis(perfluoronaphthyl)borate, triphenylcarbenium tetrakis(perfluorobiphenyl)borate, triphenylcarbenium tetrakis(3,5-bis(trifluoromethyl)phenyl)borate, or triphenylcarbenium tetra(perfluorophenyl)borate.

In another embodiment, one or more of the NCA activators is chosen from the activators described in U.S. Pat. No. 6,211,105.

The typical activator-to-catalyst ratio, e.g., all NCA activators-to-catalyst ratio is about a 1:1 molar ratio. Alternate preferred ranges include from 0.1:1 to 100:1, alternately from 0.5:1 to 200:1, alternately from 1:1 to 500:1 alternately from 1:1 to 1000:1. A particularly useful range is from 0.5:1 to 10:1, preferably 1:1 to 5:1.

It is also within the scope of this invention that the catalyst compounds can be combined with combinations of alumoxanes and NCA's (see for example, U.S. Pat. Nos. 5,153,157 and 5,453,410, European Patent Publication No. 0573120 B1, and International PCT Publications WO 94/07928, and WO 95/14044 which discuss the use of an alumoxane in combination with an ionizing activator).

Polymerization processes according to the present disclosure can be carried out in any manner known in the art. Any suspension, slurry, or gas phase polymerization process known in the art can be used. Such processes can be run in a batch, semi-batch, or continuous mode.

Heterogeneous polymerization processes (such as gas phase and slurry phase processes) are preferred. A heterogeneous process is defined to be a process where the catalyst system is not soluble in the reaction media. Alternately the polymerization process is not homogeneous. A homogeneous polymerization process is defined to be a process where at least 90 wt % of the product is soluble in the reaction media. Alternately the polymerization process is not a bulk process is particularly preferred. A bulk process is defined to be a process where monomer concentration in all feeds to the reactor is 70 volume % or more). Alternately, no solvent or diluent is present or added in the reaction medium, (except for the small amounts used as the carrier for the catalyst system or other additives, or amounts typically found with the monomer; e.g., propane in propylene). In another embodiment, the process is a slurry process. As used herein the term “slurry polymerization process” means a polymerization process where a supported catalyst is employed and monomers are polymerized on the supported catalyst particles. At least 95 wt % of polymer products derived from the supported catalyst are in granular form as solid particles (not dissolved in the diluent).

Suitable diluents/solvents for polymerization include non-coordinating, inert liquids. Examples include straight and branched-chain hydrocarbons, such as isobutane, butane, pentane, isopentane, hexanes, isohexane, heptane, octane, dodecane, and mixtures thereof, cyclic and alicyclic hydrocarbons, such as cyclohexane, cycloheptane, methylcyclohexane, methylcycloheptane, and mixtures thereof, such as can be found commercially (Isopar™); perhalogenated hydrocarbons, such as perfluorinated C₄₋₁₀ alkanes, chlorobenzene, and aromatic and alkylsubstituted aromatic compounds, such as benzene, toluene, mesitylene, and xylene. Suitable solvents also include liquid olefins which may act as monomers or comonomers including ethylene, propylene, 1-butene, 1-hexene, 1-pentene, 3-methyl-1-pentene, 4-methyl-1-pentene, 1-octene, 1-decene, and mixtures thereof. In a preferred embodiment, aliphatic hydrocarbon solvents are used as the solvent, such as isobutane, butane, pentane, isopentane, hexanes, isohexane, heptane, octane, dodecane, and mixtures thereof; cyclic and alicyclic hydrocarbons, such as cyclohexane, cycloheptane, methylcyclohexane, methylcycloheptane, and mixtures thereof. In another embodiment, the solvent is not aromatic, preferably aromatics are present in the solvent at less than 1 wt %, preferably less than 0.5 wt %, preferably less than 0 wt % based upon the weight of the solvents.

In a preferred embodiment, the feed concentration of the monomers and comonomers for the polymerization is 60 vol % solvent or less, preferably 40 vol % or less, or preferably 20 vol % or less, based on the total volume of the feedstream. Preferably the polymerization is run in a bulk process.

Preferred polymerizations can be run at any temperature and/or pressure suitable to obtain the desired ethylene polymers. Typical temperatures and/or pressures include a temperature in the range of from about 0° C. to about 300° C., preferably about 20° C. to about 200° C., preferably about 35° C. to about 150° C., preferably from about 40° C. to about 120° C., preferably from about 45° C. to about 80° C.; and at a pressure in the range of from about 0.35 MPa to about 10 MPa, preferably from about 0.45 MPa to about 6 MPa, or preferably from about 0.5 MPa to about 4 MPa.

In a typical polymerization, the run time of the reaction is up to 300 minutes, preferably in the range of from about 5 to 250 minutes, or preferably from about 10 to 120 minutes.

In some embodiments, hydrogen is present in the polymerization reactor at a partial pressure of 0.001 to 50 psig (0.007 to 345 kPa), preferably from 0.01 to 25 psig (0.07 to 172 kPa), more preferably 0.1 to 10 psig (0.7 to 70 kPa).

In one embodiment of the invention, the polymerization is performed in the gas phase, preferably in a fluidized gas bed process. Generally, in a fluidized gas bed process used for producing polymers, a gaseous stream containing one or more monomers is continuously cycled through a fluidized bed in the presence of a catalyst under reactive conditions. The gaseous stream is withdrawn from the fluidized bed and recycled back into the reactor. Simultaneously, polymer product is withdrawn from the reactor and fresh monomer is added to replace the polymerized monomer. (See for example U.S. Pat. Nos. 4,543,399; 4,588,790; 5,028,670; 5,317,036; 5,352,749; 5,405,922; 5,436,304; 5,453,471; 5,462,999; 5,616,661; and 5,668,228; all of which are fully incorporated herein by reference.

In another embodiment of the invention, the polymerization is performed in the slurry phase. A slurry polymerization process generally operates between 1 to about 50 atmosphere pressure range (15 psi to 735 psi, 103 kPa to 5068 kPa) or even greater and temperatures in the range of 0° C. to about 120° C. In a slurry polymerization, a suspension of solid, particulate polymer is formed in a liquid polymerization diluent medium to which monomer and comonomers, along with catalysts, are added. The suspension including diluent is intermittently or continuously removed from the reactor where the volatile components are separated from the polymer and recycled, optionally after a distillation, to the reactor. The liquid diluent employed in the polymerization medium is typically an alkane having from 3 to 7 carbon atoms, preferably a branched alkane. The medium employed should be liquid under the conditions of polymerization and relatively inert. When a propane medium is used, the process is typically operated above the reaction diluent critical temperature and pressure. Often, a hexane or an isobutane medium is employed.

In an embodiment, a preferred polymerization technique useful in the invention is referred to as a particle form polymerization, or a slurry process where the temperature is kept below the temperature at which the polymer goes into solution. Such technique is known in the art, and described in for instance U.S. Pat. No. 3,248,179, which is fully incorporated herein by reference. A preferred temperature in the particle form process is within the range of about 85° C. to about 110° C. Two preferred polymerization methods for the slurry process are those employing a loop reactor and those utilizing a plurality of stirred reactors in series, parallel, or combinations thereof. Non-limiting examples of slurry processes include continuous loop or stirred tank processes. Also, other examples of slurry processes are described in U.S. Pat. No. 4,613,484, which is herein fully incorporated by reference.

In another embodiment, the slurry process is carried out continuously in a loop reactor. The catalyst, as a slurry in isobutane or as a dry free flowing powder, is injected regularly to the reactor loop, which is itself filled with circulating slurry of growing polymer particles in a diluent of isobutane containing monomer and comonomer. Hydrogen, optionally, may be added as a molecular weight control. In one embodiment 500 ppm or less of hydrogen is added, or 400 ppm or less or 300 ppm or less. In other embodiments at least 50 ppm of hydrogen is added, or 100 ppm or more, or 150 ppm or more.

The slurry reactor may be maintained at a pressure of 3620 kPa to 4309 kPa and at a temperature in the range of about 60° C. to about 104° C. depending on the desired polymer melting characteristics. Reaction heat is removed through the loop wall since much of the reactor is in the form of a double-jacketed pipe. The slurry is allowed to exit the reactor at regular intervals or continuously to a heated low pressure flash vessel, rotary dryer and a nitrogen purge column in sequence for removal of the isobutane diluent and all unreacted monomer and comonomers. The resulting hydrocarbon free powder is then compounded for use in various applications.

In certain embodiments, little or no alumoxane is used in the process to produce the polymers. Alumoxane is optionally present at zero mol %, alternately the alumoxane is present at a molar ratio of aluminum to transition metal less than 500:1, preferably less than 300:1, preferably less than 100:1, preferably less than 1:1.

In a preferred embodiment, little or no scavenger is used in the process to produce the polymer, such as ethylene polymer. Preferably, scavenger (such as trialkyl aluminum, Al¹R¹⁹ ₃ as defined above) is present at zero mol %, alternately the scavenger is present at a molar ratio of scavenger metal to transition metal of less than 100:1, preferably less than 50:1, preferably less than 15:1, preferably less than 10:1.

In a preferred embodiment, the catalyst system used in the polymerization comprises no more than one catalyst compound. A “reaction zone” also referred to as a “polymerization zone” is a vessel where polymerization takes place, for example a batch reactor. When multiple reactors are used in either series or parallel configuration, each reactor is considered as a separate polymerization zone. For a multi-stage polymerization in both a batch reactor and a continuous reactor, each polymerization stage is considered as a separate polymerization zone. In a preferred embodiment, the polymerization occurs in one reaction zone.

Other additives may also be used in the polymerization, as desired, such as one or more scavengers, promoters, modifiers, chain transfer agents (such as diethyl zinc), reducing agents, oxidizing agents, hydrogen, aluminum alkyls, or silanes.

In a preferred embodiment of the invention, the polymerization occurs within the mesopores of the organosilica material support and preferably the mesopores have an average diameter as discussed above, for example, from about 2 nm to about 50 nm, alternately about 3 nm to about 20 nm.

Typically, the polymers produced herein have an M_(w) of 5,000 to 1,000,000 g/mol (preferably 25,000 to 750,000 g/mol, preferably 50,000 to 500,000 g/mol), and/or an M_(w)/M_(n) of greater than 1 to 40 (alternately 1.2 to 20, alternately 1.3 to 10, alternately 1.4 to 5, 1.5 to 4, alternately 1.5 to 3).

In a preferred embodiment the polymer produced herein has a unimodal or multimodal molecular weight distribution as determined by Gel Permeation Chromatography (GPC). By “unimodal” is meant that the GPC trace has one peak or inflection point. By “multimodal” is meant that the GPC trace has at least two peaks or inflection points. An inflection point is that point where the second derivative of the curve changes in sign (e.g., from negative to positive or vice versus).

Unless otherwise indicated M_(w), M_(n), MWD are determined by GPC as described in U.S. Publication No. 2006/0173123, at pages 24-25, paragraphs [0334] to [0341].

In a preferred embodiment the polymer produced herein has a composition distribution breadth index (CDBI) of 50% or more, preferably 60% or more, preferably 70% or more.

Such applications include, for example, mono- or multi-layer blown, extruded, and/or shrink films. These films may be formed by any number of well known extrusion or coextrusion techniques, such as a blown bubble film processing technique, wherein the composition can be extruded in a molten state through an annular die and then expanded to form a uni-axial or biaxial orientation melt prior to being cooled to form a tubular, blown film, which can then be axially slit and unfolded to form a flat film. Films may be subsequently unoriented, uniaxially oriented, or biaxially oriented to the same or different extents. One or more of the layers of the film may be oriented in the transverse and/or longitudinal directions to the same or different extents.
